It's hard to prevent intraventricular hemorrhage, aside from certain medications that can lessen risk and, of course, providing excellent care to premature babies. Other factors that can help decrease the chance of intraventricular hemorrhage include:

Giving birth in a hospital with a NICU (so babies can be more quickly treated and with minimal movement)
Delayed cord clamping or umbilical cord milking
Taking vitamin K before delivery (especially for women who may take medications that alter blood flow and increase bleeding risks)

If your baby is premature or you were particularly worried about
intraventricular hemorrhage, speak to your doctor to see what measures can be taken to help prevent and treat intraventricular hemorrhage.

Prognosis of Intraventricular Hemorrhage
The outcome depends on the severity of intraventricular hemorrhage and how premature the baby is when it develops this. The more developed a baby is, the less its risk.

Most babies who suffer intraventricular hemorrhage of grade 1 or 2 will survive, and with minimal damage.

Less than about a third of babies with grade 3 or 4 intraventricular hemorrhage die because of it or may suffer severe long-term damage.

If treated properly and caught early on though, the prognosis of most cases can be very promising.
